Abstract

The invention relates to a circuit arrangement having a switching device (1) which is designed to provide a first voltage (UE) and a first electrical current (IE) in a power path and to provide a second voltage (US) and a second electrical current (IS) in a measuring path for the duration of a switching period, wherein the first electrical current corresponds to the second electrical current; having a current measuring apparatus (2) which is arranged in the measuring path and is designed to provide an output signal (UM) which corresponds to the first electrical current; and having a control circuit (3, 4) which is designed to activate the current measuring apparatus for the duration of a measuring period and to deactivate the current measuring apparatus again after the measuring period expires.
